Flask
=====
Flask is a lightweight `WSGI`_ web application framework. It is designed
to hasten and ease the process of web application development, with the ability to scale up to
complex applications. Flask began as a simple wrapper around `Werkzeug`_
and `Jinja`_ and has become one of the most popular Python web
application frameworks.
Flask offers suggestions, but doesn't enforce any dependencies or
project layout. Developers must choose the tools and
libraries they want to use.
Many provided extensions exists to help easily add new functionalities.
